Please...don't confuse AE Prism 'II,' with the non-metered Model '2,' prism.
(Mamiya makes a major [confusing] distinction in their RZ Prisms,
employing both conventional numbers, or Roman numerals).
Check manual pages 18-19 (PDF pages 21-22) from an
RZ accessory manual provided by the 'Butkus Manuals Site.'
That list is a lot of help, thanks! My prism came and it wasn't the original RZ AE prism like I bought, but a RZII prism. Works just fine, B&H's mistake, it costs more than what I paid too!
